基于ARM处理器的高速高精度数据采集系统设计

A Design of High-speed and High-accuracy Data Acquisition System Based on ARM Processor

本文介绍了一种基于ARM7处理器的高速、高精度、多通道数据采集系统的设计和实现,首先对模拟信号调理电路设计进行了讨论,其次介绍了基于ARM处理器S3C44B0X和模数转换芯片AD7663的接口电路,并分析了数据采集部分的程序代码,最后提出了关于高精度数据采集系统PCB设计的一些经验和观点。

This paper introduces the design and implement of a high-speed,high-accuracy,muhiple-channel data acquisition system based on ARM7 technology. Analog signal conditioning circuit was discussed at first. Then introduced the interface circuit between the ARM7 processor S3C44BOX and the AD7663 analog-digital converter, and analyzed the code of the data acquisition program. Some point of view to the PCB design of the high-accuracy data acquisition system was put forward at the endof this paper.
